The suction head unit and the conveyor table are driven in the cycle of the sheet processing apparatus. Thus, it is desired that the sheets are always delivered to the sheet processing device at exactly the right time. However, depending on the quality and surface properties of the sheet, a greater or lesser degree of slippage can occur between the sheet and the conveyor belt of the conveyor table carrying the sheet. In such a case, the sheet is not delivered to the sheet processing device at the appropriate time. In other words, the actual time point of the sheet delivery and the target time point deviate.

ブルの搬送速度が最も低い時点であるようにした。SUMMARY OF THE INVENTION In order to solve this problem, according to the configuration of the present invention, the actual time of arrival at the transfer position to the sheet processing machine is determined by the position of the frontmost sheet located on the conveyor table. Paper, and can be compared to the target time, and the work cycle of the suction head unit can be corrected in the early or late direction corresponding to the difference between the target time and the actual time, The course of the movement of the conveyor table was substantially sinusoidal during one working cycle, and the target time point was the time point at which the conveying speed of the conveyor table was the lowest.

搬送速度が最も低い時点である。According to the present invention, the deviation between the actual time and the target time can be corrected. In this case, the correction is made as quickly as possible without affecting the cycle synchronism between the conveyor table and the sheet processing machine. This is because corrections are already made at the beginning of the sheet transport path. The sheet is corrected earlier or later correspondingly and delivered from the suction head unit to the conveyor table. When the sheet strikes the leading edge mark defining the transfer position at high speed, the sheet bounces off and is no longer precisely positioned and fed to the sheet processing machine. To avoid this, in the configuration of the invention, the course of movement of the conveyor table is substantially sinusoidal during one working cycle, in which case the target time point is the time point at which the conveyor table transport speed is the lowest.

As a result, the arrival at the transfer position to the sheet processing machine 11 is detected, and a corresponding signal is guided to the electronic processing unit 16 via the conductor 20. In this case, for example, the optical sensor 19 is located below the transport plane of the sheet within the range of the transfer position and emits a signal by the leading edge of the sheet when arriving at the transfer position. If the actual time of arrival at the transfer position to the sheet processing machine 11 deviates from a target time set by the work cycle of the sheet processing machine 11, this deviation is recognized by the electronic processing device and the suction The drive 12 of the head unit 5 is controlled and its working cycle is correspondingly advanced or delayed.
